基于单片机系统的(24,16)循环码编码、译码方案

　　在理论分析循环码编码和译码基本原理的基础上，提出了基于单片机系统的(24，16)循环码软件实现编码、译码的方案。仿真结果表明(24，16)循环码能有效地克服来自通讯信道的干扰，保证数据通信的可靠及系统的稳定，使误码率大幅度降低。本论文对(24，16)循环码的研究结果表明，可以有效地降低错误概率和提高系统的吞吐量，实现纠错仅需要在接收端增加有限的存储空间和计算复杂度，具有一定的实用价值。　　Abstract: 　　Based on analyzing the theory of encoding and decoding of cyclic code， this paper showed the schemes of encoding and decoding of(24，16)cyclic code by the software and based on microcontroller. Simulation results show that using (24，16) cyclic codes can effectively overcome the interference from communication channel， ensure the reliability and stability of data communication systems， and reduce the bit error rate greatly. The results of this paper show that by using the (24，16) cyclic code， the error rate can be reduced and the system throughput can be improved. Meanwhile， the system only needs to Enlarge limited storage space and computation the complexity at the receiving end to realize error correction. Thus the (24，16) cyclic code has a practical value.

　Recognizing its importance is only the fist step to advocate invetion or innovation

　Recognizing its importance is only the fist step to advocate invetion or innovation， and some effective measures should be taken for it. For one thing， our authority should continue to Enlarge the recruit of graduate. For another， the conditions of scientists and skilled workers should be further improved. Only in this way， can “the soul of our nation” be fully embodied and our nation have a brighter future.
